' WALL STRUCTURE Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed June 7, 1920.; Serial No. 386,988.

To all whom it may cmwem A Be it known that I, AUGUSTUS H. Sjrownrm, a citizen of the United States, reslding at Spokane, in Spokane county, and State of' Washington, have invented certain new and useful Improvements in Wall Structures, of which the following is a specification.

The present invention relates to an 1mproved wall structure made up of tiling and. designed especially for the lining of flumes,

ditches, &c., in irrigation operations, the primary object of the invention being the .provision of a wall or lining for the ditch that is durable, strong, comparatively cheap in cost of production, and which may be built with comparative ease and quickness, thus reducing .the factors of time and labor in v the construction work.

With the above and other objects in view the invention consists in certain novel combinations and arrangements of tiles as will be hereinafter more fully set forth and claimed.

In the accompanying drawings I have illustrated one complete example .of my invention physically embodied as an irrigation flume, in which the parts are combined and arranged according to the best mode I have thus far devised for the practical epplication of the principles of my invention.

Figure 1 is a view showing a portion of the lining of an irrigation flume, embodying the invention.

Fig. 2 is a transverse sectional view of the lining or wall.

as L, the ditch of which this lining forms a part, is semicircular in cross section, and

the tiles 1 may be laid directly on the curved surface of the ditch, or if desired a bedding of cement may first be applied to the con- 4 cave walls of the ditch and the tiles laid therein. I

The tiles are of rectangular shape and curved in cross section to conform. to the curved walls of the ditch in which they are to be laid.

At one of its sides each tile is provided with a longitudinally extending dovetail head 2 projecting below the outer surface of the tile and forming one of the walls of a recess 3 at the lower face of the tile, while the oppo slte side or edge of the tile is fashloned with an oppositely projecting key flange 4 which forms a groove 5 opening up to the upper or inner face of the tile. Thus the'bead 2 and the flange 4 project in opposite directions from the outer face of the t le, and the bead 2 on the outer face of the tile as it is built into the wall projects into the inwardly opening groove 5- of the adj oining tile forming a dovetail joint, and the edge of the flange 4 fits against the under face of the tile at the inner side of the head,

.as shown in Fig. 2.

The grooves 5 ofthe alincd tiles form contlnuous channels in the wall and the heads -2 form continuous tongues to fit in these channels extending the full length of the wall or lining L.

At one 'end ofthe tile a transverse head 6 is fashioned, similar to the head 2 but terminating a short distance from head 2 in order to afford a continuous channel and this bead also projects outwardly from the tile when the latter is in place in the lining or wall, the bead terminating or merging at one side of the tile into the flan e .4. ,At the other end of the tile a flange is fashioned and forms a groove 8 at the end of the tile, the flange depending at its base from the lower or outer face of the tile, with its edge projecting upwardly or inwardly, and as seen in Fig. 1 this flange stops short or terminates near the sides of the tile to pro vide an open end groove 8 for the reception of the transverse head 6 at the opposite end of the tile.

Preferably a metal reinforcing rod or bar 9 is placed in the bottom of the channel formed by the grooves 5, beneath the beads 2 of the tile, and cement filling is poured into all the joints of tongue and groove.

The end joints of the lining are staggered as seen in Fig. 1, and the tiles are laid in longitudinal courses as illustrated in the perspective view of the lining, and the elongated reinforcing rods in'the channels provided therefor extend a suflicient length to insure a tight locking of the parts and strengthening of the joints as they are embedded in the cement joint;

The tiles are of identical construction, and

can thus be made in quantities of production and packed and shipped with convenience,

and facility in handling. And as they are of simple construction and may be laid with perfect fits and adjustment, skilled labor is not required in the building of Walls, linings or flames.

What I claim is- 1. A lining structure composed of courses of longitudinally alined tiles, the tiles in each course having depending side flanges forming an upwardly extending continuous tongue and a continuous channel, and the tiles in adjacent courses having edge beads forming continuous depending tenons in said channel, and the ends of said tiles having oppositely projecting, transverse, interlock- ,ree

ing beads and flanges and grooves located. in the side flanges of adjoining tiles.

2. A tile having a longitudinally extending oppositel projecting bead and flange each depending from its outer face and the flange forming an open groove below the face of the tile, an outwardly projecting bead at one end of the tile and an inwardlv projecting flange at the other end of the tile forming an end groove below the outer face of the tile, said head and end flange being shorter than the width of the tile.

In testimony whereof I atfix my signature.
